Jeff
While a logic analyser was very helpful with non microcontroller logic
circuitry I have not needed one since switching to playing with micros.
Note that I'm just a hobbyist.
I picked up a Velleman PCS100 multipurpose unit once that interfaces to
a parallel printer port. After playing for less than an hour I put it
back in the box and it has sat on the shelf undisturbed ever since. The
software seemed pretty good but the logistics of needing a computer plus
the scope plus AC power made it rather cumbersome and it was slow
compared to a $300. (at the time) digital scope from saelig.com. I still
may need a booster battery pack + inverter to use the saelig scope
anywhere other than my bench but at least those are small rugged
components that I usually have handy anyway.
I now assume that anything that interfaces with a computer has a life of
only a few years due to computer and operating system upgrades etc. that
eventually increase the hassle factor too high compared to replacing the
unit.
Simplicity is important for occasional hobbyist use. Anyway don't
underestimate the value of a stand alone (possibly hand held) scope. I
avoid anything with non standard rechargeable batteries though. Speed is
important for tracking down a glitch involving a spike at the corner of
a digital signal but for me that is a rare need with microcontrollers.
Usually I'm just looking for the correct polarity, phase, voltage, or
frequency if that makes sense to you.

Hi All
I bought ages ago a PM/OV Filter and OV Protection Kit (14v) that I intended to
fit to my Jab 3300.
Now I have come to the fitting end and wonder if it is still the right part for
my Single Phase Jab 20 AMP PM?? as the wiring shows it for a 3 Phase one..
Can someone confirm if this is the correct kit for my new jab?
from their site
This 14 volt kit provides crucial over-voltage protection to our permanent magnet
alternator (BC433-H) and others rated at 30 amps or below. Comes with a clear-yellow
warning light that will illuminate if the crowbar over-voltage protection
module is tripped (or when the alternator switch is left off), and a filter
capacitor to reduce radio noise and enhance regulation.
Thanks
Chris

| Subject: | Attaching "uninsulated ring terminals" to 4 awg wire... |
I'm using the "uninsulated ring terminals" for 4 awg wire from the contractors
to my bus and alternator. Are the terminals sold by B&C meant to be crimped or
soldered? If crimped where can I get a crimper big enough to handle 4 awg. B&C
only sells ones that handle up to 10 awg wire.
Thanks,
Michael-

Michael,
Harbor Freight has a hydraulic crimper that does the job.

Works great, but do NOT go by the wire size markings on the various crimping
dies...they are WAY off the mark. (or at least were on my unit)
